Radio Notifications - undefined reference to 'sd_nvic_ClearPendingIRQ'

[RichieJH]

I am just working through the tutorial on radio notifications and imported "ble_radio_notifications.c" to my application folder and included the header in included directories.

I walked through the other steps of the tutorial but now I am unable to build and the output is saying undefined reference to sd_nvic_ClearPendingIRQ (as well as the other two sd_nvic_'s in "ble_radio_notificiation_init")

This seems strange since the user included directories is pointing to the relevant soft device headers file (as you would expect since before adding be_radio_notification it worked fine).

What am I missing?

This is nRF52, SDK11, PCA10040, SD132 2.0.0. Also using SES.

Thanks - RJH

If you actually look at the headers you're importing when you compile that file, none of them contain the definition for any of those three functions, so it's not surprising it can't find them, it is surprising that it doesn't complain at compile time, not just link time.

Add the actual header file they're in, nrf_nvic.h, to the includes.

Hi RK, quite right. I took a look at the tutorial again to make sure I didn't miss anything and I hadn't. Tutorial may need to be refreshed but I'm sure the Nordic guys have it on their list. Having solved this I've struck another snag, but that is another question. Thanks again - RJH
